Evaluation of laparoscopic management of recurrent gastroesophageal reflux disease and hiatal hernia: long term results and evaluation of changing trends

Short and long-term outcomes after pediatric redo fundoplication

BACKGROUND

Redo fundoplication (RF) is the most common surgical treatment for recurrent gastroesophageal reflux disease (GERD) in children, but outcomes after RF are rarely reported. The aim of this study was to assess short- and long-term outcomes after RF in childhood.

METHODS

The study is a follow-up study of patients undergoing RF from 2002 to 2020 at a teriary care center. Patients/parents were sent questionnaires recording symptoms of recurrent GERD, troublesome side-effects and satisfaction. Retrospective chart review was also performed.

RESULTS

24/28 (86%) patients were included median 9 (1.6 months-17.7 years) years after RF. 16 (67%) had neurologic impairment. Indications for RF was recurrence of GERD (n = 18), discomfort or dysphagia from a herniated wrap (n = 5) and dysphagia from a slipped fundoplication (n = 1). Median operating time was 128 (95-250) min. Six (25%) patients experienced early major complications, of which two were gastrostomy related. Five (21%) patients experienced recurrence after RF. Three of these were symptom free at follow-up with medical treatment or re-RF. The most common symptom at follow-up was stomach pain (37%) and excessive flatulence (38%). 18/22 (95%) patients/parents would choose RF again, and 21/22 would recommend RF to someone in a similar situation.

CONCLUSIONS

RF is successful in treating recurrent GERD after primary fundoplication, and patient/parental satisfaction is high.

Nationwide Outcomes and Readmission After Pediatric Laparoscopic and Open Fundoplication

Purpose: Fundoplications are a common operation in the pediatric population. This study aims to explore outcomes comparing laparoscopic versus open operative techniques. Methods: From 2010 to 2014 the Nationwide Readmissions Database was used to identify patients aged 0-18 years who underwent a fundoplication. Propensity score matched analysis was performed based on 87 covariates. Demographics, hospital factors, readmissions, and complications were compared by surgical technique (laparoscopic versus open). Results: There were 4411 patients (47% female) who underwent fundoplication via laparoscopic (69%) versus open (31%) technique. Gastrostomy tubes were placed in 75% of patients also undergoing fundoplication. Newborn made up 64% of the cohort, with 47% of newborns having cardiac anomalies and 96% being premature. Open fundoplications were more likely to be performed in newborns (72% versus 61%) and those in the lowest income quartile compared to laparoscopic (41% versus 31% P < .001), both P < .001. The readmission rate was 20% within 30 days and 38% within the year, with 15% admitted to a different hospital. Only 14% of readmissions were elective. Open fundoplication was associated with more unplanned readmissions (94% versus 84%), conversion to gastrojejunostomy tube (11% versus 5%) along with major (5% versus 3%) and minor (8% versus 2%) complications compared to the laparoscopic approach, all P < 0.001. Conclusion: The majority of fundoplications are being performed in newborns and are being done laparoscopically, which are associated with lower complication and postoperative readmission rates compared to open fundoplications.

Minimal esophagus dissection without approximating the hiatus in laparoscopic fundoplication in pediatric population

OBJECTIVE:

An important part of laparoscopic Nissen’s fundoplication (LNF) is a proper wrap, which may only be possible with proper dissection of esophagus and hiatus. However, too much dissection of esophagus and hiatus to gain sufficient length of esophagus increases morbidity. The aim of this study is to analyze the effect of minimal esophagus dissection in LNF on recurrence and post-operative hiatal hernia.

METHODS:

The present study includes the children (0–18 years) who underwent LNF with minimal esophagus dissection and without hiatal closure between 2008 and 2016. The charts of the patients analyzed retrospectively and evaluated in terms of recurrence and post-operative hiatal hernia.

RESULTS:

There were 143 children. Mean age was 4.5±4.6 year (20 days–17 years). About 54% of the children (n=78) were neurologically impaired. There were two temporary intestinal obstructions which did not require surgery, one esophageal tightness which resolved with one dilatation session and one recurrence with hiatal hernia which required reoperation.

CONCLUSION:

Minimal esophagus dissection without hiatal closure in LNF avoids dysphagia with no increase in the rate of recurrence and complications.

Quantitative assessment of crural closure for laparoscopic anti-reflux surgeries: A novel technique to reduce post-operative dysphagia

Background:

Long-term dysphagia is a known complication of laparoscopic anti-reflux surgery (LARS). Of the several factors, inadequate hiatal closure is one of the major reasons for its occurrence. The aim of this study is to develop a technique for the quantitative assessment of crural closure during LARS to reduce dysphagia.

Materials and Methods:

It is an analysis of prospectively collected data of 109 patients who underwent LARS at a tertiary healthcare centre in India. To identify the adequacy of hiatal closure intraoperatively, a 7 French Fogarty catheter was used, and its balloon was inflated with 1 cc air at the repaired hiatus. This inflated balloon in the repaired hiatus following cruroplasty gives an accurate quantitative assessment of the adequate closure and adequate space for food bolus to pass without causing mechanical obstruction after hiatus repair. Pre- and post-operative 12 months’ DeMeester scores and lower oesophageal sphincter (LES) pressures were calculated.

Results:

The patients had a significant reduction in DeMeester scores postoperatively from a mean of 68.5–12.3 (P < 0.0001). None of the patients had long-term dysphagia or the need for long-term proton-pump inhibitors. The mean LES pressures on post-operative manometry showed increase to 15.1 mmHg from a mean of 6.4 mmHg, which was statistically significant (P = 0.0001). None of the patients had a recurrence of hiatus hernia.

Conclusion:

Quantitative assessment of adequacy for crural closure during LARS using a 7 French Fogarty catheter balloon is a novel technique which may decrease the incidence of post-operative dysphagia or intrathoracic wrap migration or recurrence of hiatus hernia.

Indications for total esophagogastric dissociation in children with gastroesophageal reflux disease

Total esophagogastric dissociation (TED) is used to treat gastroesophageal reflux (GER) after failed fundoplication in neurologically impaired patients. It is now performed for some otherwise healthy patients with severe GER. In this procedure, the gastrointestinal tract is reconstructed in a non-physiological way with a Roux-en-Y esophagojejunal anastomosis and jejuno-jejunostomy. Although TED eliminates almost all GER, some patients experience late complications. In this review, we investigated the long-term outcomes after TED to determine the best indications. In total, 147 neurologically impaired patients and 28 neurologically normal patients were identified. The total rate of complications requiring re-operation was 17.2% in neurologically impaired patients and 32.1% in normal patients, both higher than the rates associated with fundoplication. Although most authors added pyloroplasty when there was a concern of gastric emptying, this sometimes caused bile reflux. Nutritional and metabolic complications, including dumping syndrome and chronic digestive malabsorption, were also reported to occur after TED. TED is an option for the treatment of neurologically impaired patients with recurrent GER after fundoplication or who are at a high risk of recurrence of GER with fundoplication. However, neurologically normal patients who have the ability to obtain nutrition orally should consider options other than TED, as postoperative complications are frequent.

Fundoplication

Gastroesophageal reflux disease (GERD) is a common condition in infants. Symptoms from pathologic GERD include regurgitation, irritability when feeding, failure to thrive, and respiratory problems. Treatment typically starts with dietary modifications and postural changes. Antireflux medications may then be added. Indications for operative management in neonates and infants include poor weight gain, failure to thrive, acute life-threatening events, and continued respiratory symptoms. Laparoscopic Nissen fundoplication has become the standard of care for surgical treatment of children with GERD. In this procedure, the fundus of the stomach is wrapped 360° posteriorly around the lower esophagus.

Fundoplication in Patients with Esophageal Atresia: Patient Selection, Indications, and Outcomes

Patients with esophageal atresia (EA) suffer from abnormal and permanent esophageal intrinsic and extrinsic innervation that affects severely esophageal motility. The repair of EA also results in esophageal shortening that affects distal esophageal sphincter mechanism. Consequently, gastroesophageal reflux (GER) is common in these patients, overall approximately half of them suffer from symptomatic reflux. GER in EA patients often resists medical therapy and anti-reflux surgery in the form of fundoplication is required. In patients with pure and long gap EA, the barrier mechanisms against reflux are even more damaged, therefore, most of these patients undergo fundoplication during first year of life. Other indications for anti-reflux surgery include recalcitrant anastomotic stenoses and apparent life-threatening episodes. In short term, fundoplication alleviates symptoms in most patients but recurrences are common occurring in at least one third of the patients. Patients with fundoplication wrap failure often require redo surgery, which may be complicated and associated with significant morbidity. A safe option in a subset of patients with failed anti-reflux surgery appears to be long-term medical treatment with proton pump inhibitors.

Current status of surgical management of gastroesophageal reflux in children

PURPOSE OF REVIEW

Surgical therapy for gastroesophageal reflux disease (GERD) is controversial with considerable debate ranging from the indications for antireflux surgery to surgical technique. This article will attempt to clarify these issues with the most up-to-date information available on the prevalence, pathophysiology, diagnosis, and surgical treatment of GERD in children. Although laparoscopic Nissen fundoplication (LNF) has become the most popular operation performed for pathologic reflux, its superiority over both open surgery and other types of fundoplication is not well established.

RECENT FINDINGS

Large retrospective studies suggest LNF has a lower complication rate than open surgery. However, three prospective randomized controlled trials have been published recently which cast doubt on the superiority of LNF and suggest that LNF may have a higher failure rate compared to open fundoplication. Antireflux surgery has higher morbidity and failure rates in infants and in children with neurologic impairment.

SUMMARY

Based on the best available evidence, LNF may be less morbid, but have a higher rate of failure than open surgery. Pediatric surgeons should be mindful of the risks and benefits of both approaches to best counsel their patients. Larger prospective randomized controlled trials are needed to determine the best treatments for pediatric GERD.

[Management of gastroesophageal reflux in children. Single centre experience in conventional and laparoscopic Nissen fundoplication in the last 15 years]

INTRODUCTION

Nissen fundoplication (NF) is the most used and effective technique for the treatment of gastroesophageal reflux in children. The laparoscopic approach (LNF) is safe, with low morbidity and high success rate, although some cases require a conventional approach (CNF). The aim of the study is to compare the results between LNF and CNF in our centre.

MATERIAL AND METHODS

A retrospective review was performed on patients <14years after NF between 2000 and 2015. A comparison was made of the complications, hospital stay, and follow-up for both approaches.

RESULTS

Of the total 75 NF performed, 49 (65.3%) were LNF, 23 (30.7%) CNF, and 3 (4.0%) reconversions. Concomitant laparoscopic gastrostomy was performed in 10.7%, and open gastrostomy in 5.3% of cases. Prior to NF, 10.7% had a gastrostomy. The mean age was 4 years and 68.7% were male. Of the diagnoses, 36% had encephalopathy, 14.7% hiatal hernia, 5.4% oesophageal atresia, and 5.4% an acute life-threatening event. No differences were found in operation time. More than two-thirds (36%) had complications, which were more frequent in the CNF (OR=3.30, 95%CI: 1.1-9.6). The hospital-stay decreased by 9 days in the LNF (95%CI: 5.5-13.5). Mean follow-up was 26 months (95%CI: 20.9-31.6). Mortality during follow-up was of 5.3% (5 respiratory failure, 1 sudden cardiac death, and 2 due to complications of the encephalopathy), 4.2% required re-fundoplication, 15.8% had symptomatic improvement, and 64.0% had absence of symptoms.

CONCLUSIONS

The LNF is an effective technique for the treatment of gastroesophageal reflux, with lower morbidity and shorter hospital stay than CNF. It is recommended as the first surgical option.

A New Sliding-Loop Technique in Renorrhaphy for Partial Nephrectomy: A Feasibility Study in a Porcine Model

BACKGROUND

We developed a sliding-loop technique that narrowed both sides of the parenchyma in a porcine model and compared it with the conventional sliding-clip technique.

METHODS

Three pigs (30-40 kg) were reused following another experiment conducted by the same researchers. Bilateral kidneys were harvested within 30 minutes after euthanasia. Two partial nephrectomies per kidney were performed on opposite surfaces. All kidney defects were of the same size (diameter of 2.5-3 cm with a depth of 1.0-1.5 cm). The sliding-clip technique and sliding-loop technique were performed separately. In the sliding-loop technique, we created a 1-cm loop at the end of a Vicryl and placed a tetrafluoroethylene polymer pledget in front of the knots passing through the needle. The needle then crossed the loop after passing through the renal parenchyma. A Weck clip was placed and slid on one side to tighten the suture. Tightening was controlled with an equivalent force using a digital push-pull gauge. Three stitches were placed at each renorrhaphy site. The distance between repaired renal surfaces was measured at 5 different points (3 suture sites and 2 middle sites between sutures).

RESULTS

The results of the 2 techniques were compared by using the independent t test. The mean distance between renal surfaces was significantly narrower in the sliding-loop technique than in the conventional technique (1.80 ± 1.08 mm vs 5.28 ± 2.46 mm, P < .001).

CONCLUSION

In the porcine model, the sliding-loop technique more effectively closed the partial nephrectomy defects compared with the conventional sliding-clip technique.
